Riverfront development Case Study

Master Plan

Sewage contaminated storm water out-falls along with dumping of industrial waste.Though a major source of water for the city and despite the building of a major barrage to retain water, except for a few months the river is dry.The riverbank slums are disastrously flood prone and lack basic infrastructure services.The slums located along the riverbed also pose a major impediment to efficient management of monsoon floods in the riverDESIGN PROBLEM

Revitalize the center of Ahmadabad

Create an identity of AhmadabadImprove housing for the poor

NRCP : In Brief To stop sewage from entering the river through the storm water drainage system.

It proposed- interception and diversion worksthe construction of trunk sewers and pumping stations in the periphery of the citythe desilting of storm water drains.the up-gradation of existing sewage treatment plants.the provision of sanitation infrastructure in river bank slums.

INITIAL PROPOSALS..The Ahmadabad Municipal Corporation (AMC) set up the Sabarmati Riverfront Development Corporation Ltd (SRFDCL) in May 1997.

The AMC appointed the Environment Planning Collaborative (EPC), an Ahmadabad-based urban planning consultancy firm, to prepare a plan.

First Phase: EPC identified a 9 km stretch of the riverfront extending from Subhash bridge to Vasna barrage and proposed to reclaim 162 hectares (400acres) of the riverbed.

After observing 2006 flood and its impact ; land use plan added Subhash bridge to Dafnala so total reclaimed land is now 202 hectare.

The average width of the Sabarmati channel was 382 metres (1,253ft) and the narrowest cross-section 330 metres (1,080ft) ; to develop the riverfront, SRFDCL had uniformly narrowed the channel to 275 metres (902ft).

Lower promenade..

Pedestrian walkway that provides public access to sabarmati river and creates a space for recreational activity.

Interceptor Sewers..

It will redirect the flow of sewage to sewage treatment plants at Vasana and Pirana ;preventing sewage to drain from storm water pipes into river.

Retaining wall ..

In addition to supporting the reclaimed land and new development ,the retaining wall, stands taller than the HFL , protecting the city in case of high floods.

Relocation housing ..

Project boundary ..

General fill..

The earth filling creates a base foundation to develop infrastructure , promenades,gardens,roads and buildings.

Infrastructure ..

(SRFDCL) have a 500-metre-long tunnel on the drawing board, designed for smooth traffic flow between Nehru Bridge and Ellisbridge on the east bank of the river.On the western side of the river, a 4 lane wide road West River Drive will be constructed at Subhash Bridge, Gandhi Bridge and Sardar Bridge, while on the Eastern side, a 6 lane wide road East River Drive will come up at Dudheshwar Bridge, Gandhi Bridge and Sardar Bridge.PROPOSED ROAD NETWORK

Gardens and public spaces

Almost 40% of the land on banks for garden.Theme based parks and gardens from Vasna barrage to Subhas bridge.

Stone posts in the garden will provide info on important dates and events in history and insights into the life and times of Gandhi

a sundial will be another feature

No concept of Floor Space Index (FSI) on Sabarmati Riverfront for now.the 20-per cent of land reserved for commercial development has perfect pre-decided geometrical plot shapes that would define the shape of building coming on them and each shape has been assigned the number of floors to go with it.The saleable built-up area is calculated as a multiple of the area of the footprint and the number of floors assigned to each of the plot shape.No compound wall; slot for parking within the premises and there would be public parking spaces alsoFor the design effect, buildings in shapes of circles, square, rhombus and quadrilaterals are planned in prime real estate zones

Riverside development..

Approx. 15% of buildings along riverfront will be sold for commercial ,residential, retail and recreational development in order to finance the project.

Adjacent areas..



The Hudson river is one of the rivers that is part of the New York Harbor Estuary. It starts at Mount Marcy; which is the source.The mouth of the Hudson is the at the Battery in NYC. The Hudson river also is combined with the East river, and flows into the Atlantic Ocean. The Hudson flows 315 miles fromMt. Marcy to southern Manhattan.It has living organisms like cod, oysters, and plankton, and is safe for boating and swimming.


Originally a working waterfront. Much of riverfront left as an area of abandoned industrial portlands.

Other reasons:The lack of automobile connections and the environmental degradation of the region.Lack of effort to enhance environmental and cultural resources in the region.Waterfront walks and parks and mixed uses which allow such walks and parks are desired by area residents.

Dutch settlers cross theHudson Rivernear Fort OrangePROBLEM..

The five-mile area from Battery Place to 59th Street will share a number of common design elementsto create a unified identity for the overall park.Strong pedestrian and vehicular links between urban center and riverfront.Since each of the neighborhoods bordering the park has a distinctive look and personality, the Trust has selected different designers for each geographic area or "segment. - In the south, Segments 2/3 (Lower Manhattan and Tribeca) designed by Sasaki Associates, followed by Mathews Nielsen. - Segment 4 (Greenwich Village) by Abel Bainnson Butz. - Segment 5 (Chelsea) by Michael Van Valkenburgh Associates. - Segments 6/7 (Midtown and Clinton) by Richard Dattner Architects/ Miceli Kulik Williams Joint Venture.

DESIGN PROBLEM..In October of 2003,a Federal Environmental Protection Agency ban on discharging sewage waste from boats on the hudson river was put into effect.Grey water recycling systems.Encouraging the use of fluted pilings in place of in place of smooth pilings so as to provide additional habitat.Encouraging the construction of riverfront walkway with more eco-friendly bulkheads with increased slope/mass to provide habitat for marine plants and animals.Designation of the riverfront zone that encourages smarter , greener buildings with self-contained alternative energy sources.UNITED STATES ENVIRONMENTAL PROTECT-ION AGENCY started sediment dredgingoperat-ions to clean up the PCBs on May 15, 2009


BUILT RIVERFRONT- Areas that privoritize water dependent and water enhanced uses that are accesible to public;include lively,mixed use pedestrianfriendly pubblic destiantions.

Natural areas: natural vegetation preserved,human use retricted to walkways.Shoreline consist of intact vegetative buffer.Community park: include recreational usesSurface treatments include a combination of turfs,gardens,natural areas,hard and soft walkways.

Community greenways : areas serve as linear movement corridor as well as for passive uses as walking,fishing and water enjoyment.

Along all shorelines except at built riverfronts a vegetated greenway maintained along the river that extends to 100 year flood plain boundary

In built riverfront adjacent to municipal centres maintain a 70 foot area from the top of the riverbank ,limited to publicly accessible water dependent and water enhanced uses and includes a 16 wide walkway along the river.
